Statistical research on fingerprint identification and the testing of automated fingerprint identification system (AFIS) performances require large numbers of forensic fingermarks. These fingermarks are rarely available. This study presents a semi-automatic method to create simulated fingermarks in large quantities that model minutiae features or images of forensic fingermarks. This method takes into account several aspects contributing to the variability of forensic fingermarks such as the number of minutiae, the finger region, and the elastic deformation of the skin. To investigate the applicability of the simulated fingermarks, fingermarks have been simulated with 5-12 minutiae originating from different finger regions for six fingers. An AFIS matching algorithm was used to obtain similarity scores for comparisons between the minutiae configurations of fingerprints and the minutiae configurations of simulated and forensic fingermarks. The results showed similar scores for both types of fingermarks suggesting that the simulated fingermarks are good substitutes for forensic fingermarks.
指纹识别的统计研究以及自动指纹识别系统（AFIS）性能测试需要大量的法医指纹。而这些指纹很少能获取到。本研究提出了一种半自动方法，可大量创建模拟指纹，这些模拟指纹能模拟法医指纹的细节特征或图像。该方法考虑了导致法医指纹变异性的几个因素，如细节特征数量、手指区域以及皮肤的弹性变形。为了研究模拟指纹的适用性，针对六个手指，模拟了具有5至12个源自不同手指区域的细节特征的指纹。使用AFIS匹配算法来获取相似性分数，以比较指纹的细节特征配置与模拟指纹和法医指纹的细节特征配置。结果表明，两种类型的指纹得分相似，这表明模拟指纹可很好地替代法医指纹。
